Color/Gender of these 10 week old Wayndottes and Cochin?

[Amy_in_WV]

This is my first time raising chickens. I adopted them at 2 weeks old after my (adult) daughter lost 6 ducklings in a massacre and decided she was done trying to keep poultry. She told me the two black chicks were Wyandottes and the gray one was a silkie. It's definitely not a silkie. After lots of googling, I'm thinking standard cochin and I'm pretty sure it's a cockerel. (His/her name is Nugget. He/she acts like a big feathered puppy dog.)
The darker Wyandotte is Igor. He/she is much smaller than the one with more color (Betsy or maybe....Burt?). I'm back and forth in whether these two are pullets or cockerels. I'm also not sure if they're GLW or BLRW's. I'm hoping those of you with more knowledge might give me your thoughts. Thank you!

Nugget? He or She? Cochin?

Igor (less color) Betsy/Burt - He or she? GLW or BLRW?

And just because they're too cute not to share, here are my 3 "little chicks". I enjoyed raising the "big 3" so much that my husband agreed to 3 more.
These chicks are 4 weeks old. I'm not sure what the black and buff/red chicks are. They came from the assorted banham bin at Rural King. I'm hoping conchin bantams. I'm not even gonna worry about trying to sex them yet. I figure I'll let them get a little bigger and then ask.

Hi Amy, I give you a bump to the top.
Betsy thinks there’s something suspicious going on

I'm new at raising chickens too and not gonna be a whole lot of help with the cute chicks you have, except for the last pic of the white chick. That one is a Silkie. I have one just like it!!
Good luck with your new little ones!!!!!
